The USB interface provides communication from the Chirp 3200 to the PC. It is a full speed 2.0 (12Mbps)
connection. The connection will mate with any standard USB cable.

System Connection
3.4.1
Peripherals
All peripherals are connected directly to the PC and the setup for each is via the EchoControl Client software
application.
3.4.2
Data Logging
Same as the peripherals, any connection to an external data logger is done through the PC. There also is the
capability to run the data logging package on the same PC that your EchoControl software is operating on.

Transducer Installation
The correct transducer installation is essential to maintain good system performance. Three are three common
types of transducer installations:
1) Over-the-side
2) Through Hull
3) Sea Chest
3.5.1
Over-the-Side
The method of mounting the transducer over the side of the boat is primarily used for temporary installations. This
usually entails the transducer mounted to the end of a pole that is fastened to the side of the boat. The majority of
the transducers that are sold by Knudsen Engineering Limited have the option to be purchased with a mounting
adapter. The adapter provides a small mounting stem made of a 1-1/4" aluminum pipe with a standard pipe thread.
The longer pipe and the means to fasten it to the boat are not provided as they change with every installation. It is
very important that the transducer will be completely submerged below the water surface at all times.
3.5.2
Through Hull
A more permanent means of mounting the transducer is through the hull. This will require modifications to be
made to the hull of the boat. The face of the transducer will become the “wet end” in direct contact with the water
and the cable end of the transducer will become the “dry end” inside the hull of the boat. The location of where the
transducer goes through the hull has to be selected to prevent any type of aeration coming in contact with the
transducer face. Any modifications that are to be done to the boat to install the transducer through the hull should
be made by a qualified individual.
